READ THIS FIRST:

Check the pack and make sure you have all of the parts listed on the front of this booklet. If not, contact the outlet where you bought this product.
This product must be installed by a competent person in accordance with the current building and IEE wiring regulations.
As the buyer, installer, and/or user of this product it is your own responsibility to ensure that this fitting is fit for the purpose for which you have intended it. Eterna Lighting cannot accept any liability for loss, damage, or premature failure resulting from inappropriate use.
This product is designed and constructed according to the principles of the appropriate British Standards and is intended for normal domestic service. Using this fitting in any other environment may result in a shortened working life, for example where there are prolonged periods of use or higher than normal ambient temperatures such as lighting public or shared spaces or in nursing /care home facilities. Switch off the mains before commencing installation and remove the appropriate circuit fuse or lock off MCB.
This product is suitable for use in living areas, Bathroom Zone 2, and outsides of zones.
If being fitted in a bathroom a 30mA RCD must be used. Eterna CHA18EM3
Emergency Power and Colour Temperature Selectable Circular LED Ceiling Wall

This product is designed for permanent connection to fixed wiring: this must be a suitable circuit (protected with the appropriate MCB or fuse).
This product is suitable for installation on surfaces with normal flammability e.g. wood, plasterboard, and masonry. It is not suitable for use on highly flammable surfaces (e.g. polystyrene, textiles).
Before making fixing the hole(s), check that there are no obstructions hidden beneath the mounting surface such as pipes or cables.
NOTE: In warm white (3000K) and daylight white (6500K) operation only one set of LEDs will illuminate, in cool white (4400K) both sets of LEDs will illuminate.
The chosen location of your new fitting should allow for the product to be securely mounted (e.g. to a ceiling joist) and safely connected to the mains supply (lighting circuit).
When making connections ensure that the terminals are tightened securely and that no strands of wire protruding. Check that the terminals are tightened onto the bared conductors and not onto any insulation.

This product is double insulated. Do not connect any part to Earth.
This product is not intended to be used by children and persons with sensory, physical, and/or mental impairments that would prevent them from using it safely.
You are advised at every stage of your installation to double-check any electrical connections you have made. After you have completed your installation there are electrical tests that should be carried out, these tests are specified in the current IEE wiring and building regulations.

INTRODUCTION:

The ceiling/wall light incorporates a microwave sensing device that continuously scans the operating zone and immediately switches the light on when it detects movement in that area.
This means that whenever motion is detected within the range of the sensor the light will switch on automatically and illuminate the area you have selected to light. While there is a movement within range of the unit the light will remain on.
A microwave sensor is an active motion detector emitting high-frequency electromagnetic waves at 5.8GHz and receiving their echo. The sensor detects a change in the echo pattern within its detection zone and the light is then triggered. The wave can pass through doors, glass, and thin walls and will continually monitor the signal within the detection area. Eterna CHA18MW
Colour and Wattage Adjustable LED Ceiling Light

INSTALLATION:

Choose the location for your new fitting according to the conditions listed opposite.

Hold the base of the fitting and gently turn the diffuser and decorative trim anti-clockwise and lift off.
Loosen the screw on the LED turnbuckle and rotate to release the tray which will then hinge to allow access to the wiring terminals.
Drill holes in the back of your fitting for your fixing screws, take care and drill gently to ensure a clean hole through. Use a drill bit sized appropriately to your fixing screws.
Using the back of your fitting as a template, mark the position of your fixing holes on your mounting surface.
Prepare the holes in your mounting surface as appropriate for your fixings.
Pierce the rubber grommet in the back of your fitting making a hole just large enough to make a tight fit around the incoming mains cable.
Thread the cable through the grommet and offer the fitting to the ceiling/wall.
Secure the fitting in place. Note, if protection against ingress of moisture is required, the heads of screws must be covered with silicone or similar sealant.
Check that the grommet is still correctly fitted in the cable entry hole and around the incoming cable.
Make the electrical connections to the terminal block according to the markings:
Brown to live (L)
Blue to neutral (N)
Set power to the desired option by selecting the appropriate switch setting on the driver: 9W / 14W / 18W options
Set color temperature to the desired option by selecting the appropriate switch setting on the driver.
DL| Daylight| 6500K
---|---|---
CW| Cool White| 4400K
WW| Warm White| 3000K
Set desired settings on microwave.
Replace gear tray and secure in position.
Offer the diffuser and decorative trim onto the top of the fitting and turn clockwise until they are held securely.
Restore the power and switch it on.

UNDERSTANDING THE CONTROLS:

REFER TO THE MICROWAVE SENSOR PICTURE OPPOSITE
The sensor is an active motion detector: it emits a high-frequency electromagnetic wave 5.8GHz and receives its echo. The sensor detects the change in echo from movement in its detection zone. A microprocessor then triggers the switch light ON command. Detection is possible through doors, panels of glass, and thin walls.

DETECTION RANGE:
This determines the effective range of the motion detector and is set up by DIP switches at the sensor itself, refer to figure. Note that reducing the sensitivity will also narrow the detection range.

II| –| ON| ON| 75%
III| ON| –| ON| 50%
IV| –| –| ON| 25%
V| –| –| –| 10%

HOLD TIME:
This determines the time the fitting remains at 100% level on motion detection and is set with DIP switches at the sensor itself, refer to figure. The walk test settings (5sec) is useful when installing the fitting to establish correct operation and range.

DAYLIGHT SENSOR:
This setting holds off the 100% light output should there be sufficient daylight and is set using DIP switches at the sensor, refer to figure.

If the daylight sensor is disabled the sensor will turn on light once motion is detected regardless of the ambient light level.
